Value Collection HC3XX30100-001BX M30 Hex Cap Screw Grade 316

Product Description

The VALUE COLLECTION HC3XX30100-001BX is a fully threaded hex head cap screw manufactured to DIN 933 standards in Grade 316 Austenitic Grade A4 stainless steel. With a thread size of M30 x 3.50 and a length under head of 100 mm, this fastener is built for high-load metric bolting applications where corrosion resistance is critical. The bright, uncoated finish preserves the natural surface of the 316 stainless steel, making it well suited for environments exposed to moisture, chemicals, or salt. Maintenance mechanics, industrial technicians, and structural installers rely on this screw in applications where metric fastener specifications and material grade must be documented and verified.

This cap screw is used in industrial, marine, chemical processing, and food-service environments where 316 stainless steel is specified for its elevated molybdenum content and superior resistance to chloride corrosion. The M30 thread diameter and 100 mm length under head make it appropriate for heavy structural assemblies, equipment mounting, and flange connections requiring a large-diameter metric fastener. It is sold individually, making it practical for repair and maintenance work where single-piece replacement is needed.

Key Features

• Grade 316 Austenitic Grade A4 stainless steel for strong corrosion resistance in harsh and wet environments
• Fully threaded per DIN 933, providing maximum thread engagement across the full 100 mm length
• M30 x 3.50 metric thread size with a 46 mm hex drive for high-torque wrench engagement
• Bright, uncoated finish — no plating to chip, flake, or contaminate contact surfaces
• Metric thread standard with documented material grade for traceability in regulated installations

Compatibility

Designed as a metric DIN 933 hex head cap screw for use in any M30 x 3.50 tapped hole or matching hex nut application requiring Grade 316 stainless steel material compliance.

Installation Notes

Installation is performed by millwrights, pipefitters, or maintenance mechanics using a 46 mm open-end or box wrench. Confirm thread engagement depth and mating material compatibility before installation. In stainless-to-stainless assemblies, apply an appropriate anti-seize compound to prevent galling during torquing. Always verify that the joint design and applied torque align with the applicable engineering specification for the assembly.
